Yes, they can, but there's a right way and a wrong way to do it. A client named Marco came to me last spring with exactly this problem - his grandmother's wedding band, a beautiful 2.5mm 14k yellow gold comfort-fit band, had been stuck on his ring finger for twenty years. His knuckles had gotten bigger with age, and the ring was literally cutting off circulation. He couldn't wear it anymore. He didn't want a new ring; he wanted to wear that one.
What actually works
The short answer is that a custom ring can be built to fit over a knuckle while still being snug enough on the finger not to spin or fall off. The trick is in the engineering, not just the sizing.
For Marco's ring, I cut the shank at the bottom, added a hinged mechanism with a small spring-loaded latch, and reinforced the hinge points with 18k white gold (harder than 14k for that small joint). The ring now opens like a tiny gate, slides over his knuckle, and closes tight against his finger. The hinge is invisible from the top. He cried a little when he put it on. I didn't, but I came close.
Three approaches, from simplest to most involved
- Comfort-fit band with slightly larger sizing. This works only if the knuckle-to-finger ratio is small - say, a size 9 knuckle with a size 8 finger. You size the ring to the knuckle, then add a thin sizing bar or small beads inside the shank to keep it from spinning. It's a $50-$100 adjustment. It is not a solution for large knuckles.
- Split shank or open shank design. The ring has an opening at the bottom of the band, typically held together by friction or a small set screw. These are elegant but not for daily wear if you're hard on your hands - the screw can loosen, and the gap can snag on things. I've made two of these in the past five years and neither client has regretted it, but both are careful about when they wear them.
- Hinged shank with a clasp. This is the gold standard for arthritic fingers or significant knuckle enlargement. A jeweler cuts the band, installs a hinge on one side and a latch (usually a spring-loaded tab or a small hook) on the other. The ring opens, you slide it on, it closes. Done right, it's invisible and feels solid. Expect to pay $200-$500 for the modification, depending on the metal and complexity.
What about the setting itself?
The bigger constraint is the mounting. If the ring has a lot of stones - especially a full pave shank or a halo with small diamonds - the hinge has to go somewhere, and that somewhere is usually the bottom of the shank, which means you lose stones there. A plain metal band or a single-stone solitaire is the easiest candidate. A ring with stones all the way around? That's a much harder conversation. You might need to replace the entire mounting.
What I won't do
I won't cut a tension-set ring to add a hinge. The tension that holds the stone is distributed around the entire shank; cutting it releases that tension and the stone drops out. I won't do it on a ring with stones set into the gallery either - too much risk of cracking. And I won't promise a hinge will work on a size 4 finger with a size 7 knuckle. The mechanics just don't scale that way; the ring would have to be too thin at the hinge point.
The honest timeline
For a simple hinge job on an existing plain band, figure two to three weeks. For a full custom ring built from scratch with a hidden hinge - six to ten weeks, same as any custom piece. I've had to rush one for a client who needed to be able to remove her ring for a medical procedure; we did it in three weeks by laser welding instead of torch, and I won't pretend that's typical.
A word for the client, not the ring
If you have arthritis or joint stiffness, talk to your jeweler about it before you buy or design the ring. Do not let them just size the ring up and call it done. A ring that's too big will spin, catch on things, and drive you crazy. A ring with a proper hinge or split shank will feel like it belongs. Marco's ring, with that spring latch - he wore it to his granddaughter's wedding last fall. Said it didn't pinch once.
